Assertion : There is exchange in internal energy in a cyclic process.
Reason : Cyclic process is the one in which the system returns to its initial state after a number of reactions.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of(A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of(A).
C. If(A) is incorrect, but (R) is correct.
D. If both (A) and (R) are incorrect.

Answer

A

Explanation

As internal energy is a state function so its value depends on initial and final states of the system. In case of cyclic system initial and final states are same. So `Delta U=0, `and similarly `Delta H = 0.`
